Beit known that I, EDWARD H. DoNHoE,

a citizen of the United, States,v residing at o eoria, in the countyof Peoria and Statej of Illinois,have inventedcertain Inew and useful Improvement-sain lW'aste-Pipe yFit-` tings,3of which ythe following is a specification. f,

This invention has reference more particularly to a waste pipe fitting which is designed to avoid siphonage.`

The object of my inventionis to provide a fitting which has a number of inlets, with. means to prevent siphonage` of the inlets which has heretofore been experienced,`

and which has a tendency to drain the traps. A further object is the provision of a one piece ttin which is furnished with inlets for closet, ath, bowl, and other xtures as required, and is provided with integral means for counteracting the siphonage oreated by the closet inlet so as to prevent draining of the traps of the tub, bowl, etc.

A further object is the provision of a fitting with the fixture inlets and with anti- Siphon, means constructed in a compact manner so that the fitting will readily be contained within the ordinary partition.

My invention also embraces other objects which will appear from the following specification taken in connection with the drawing and which are particularly pointed out in the claims.

In the accompanying drawing, Figure 1 is a top sectional view of the fitting taken on the line A-A of Fig. 2 and shows in dotted lines, a bath tub, closet, bowl and sink which is connected to the fitting; Fig. 2 is a side view of the fitting; Fig. 3 an enlarged top view of the fitting; and Fig. 4 a vertical sectional view taken on the line B-B of Fig. 3.

This fitting consists of a section of vent pipe, 1 which is provided at its upper end with a hub 2, adapted to receive and connect with another section of pipe 4, and is constructed at its lower end as at 3 so as to fit within the hub of the pipe 4A, through which the waste water passes and is discharged.

This fitting is adapted to occupy an upright position and fit within the ordinary partition 6,V intermediate of the studding 7 and the wall surfaces 8 so as to be entirely concealed. The lower end of the fitting eX- tends below the ooring 9 and is provided at its lower end between the Hoor 9 and ceil- Specification of Letters Patent.

Patented Oct. 22, 1918.v

Application iiled July 15, 1914. -Seria1No. 851,062;

ing l13,with va large inlet 10, which is de signed tobe connected by means of pipe 11, with the closet, indicated by dotted lines at 12 in Fig.. 1. Y

Immediately adjacent the closet inlet 10- is an inlet14 which is connected by'means ofthe pipel 15to the tub indicated bydotted linesat-l in Figi, said pipe 15 being providedwith the usual trap 17. The tub 16,

similarlyk to the closet 12 is mounted directly on the floor 9 and the drain pipe 15 is conceale'd between the flooring 9 and. theceilin 13, and consequently is connected with the pipe 1,' approximately on ahorizontal quence the rush of water through the inlet 10 and past the inlet 14 creates a suction in the pipe l5I which unless counteracted will drain the trap 17 and permit waste gases to pass through the pipe 15 from the waste pipe. To prevent this suction I have provided a vent pipe 18, which is preferably cast integral with the fitting 1, and connected at its lower end to the inlet 14, and at its upper end to the fitting 1, immediately below the hub 2. This vent pipe 18 is preferably built very close to the fitting 1, so as to be as compact as possible and permit the placing of same in the wall and between the studding 7. Thus it will be observed that the suction created by the rush of water into the inlet 10 and past the mouth of the inlet 14 will be relieved by the air by-pass 18, which will permit air to pass from the upper portion of the fitting 1 down into the inlet 14 immediately adjacent its connection with the fitting l.

Somewhat above the Hoor 9, at the proper height for connection of same thereto the fitting 1 is provided preferably at 90 degree distances around the pipe with bosses 19, which may be drilled and tapped to rovide connection of the waste pipe 20, om the bowl 21 thereto, and the waste pipe 22 from the sink 23 thereto or the 'waste pipes from any otherxture that may be desired.

What I claim is:

1. In a device of the class described, a plumbing fitting comprising a main drain section, a closet drain communicating with the lower end thereof, a second inlet member communicating with said section at a point removed but within the vertical area and within siphoning distance of the closet drain, a vent member disposed with relation to the closet and second drain to vent the 'Q Lee same7 the upper end of said vent exhausting into said main drain section and facilities for the connection of one or more Waste pipes directly with said main section intermediate. the closet and second Waste entrances and the point Where the vent mei ber communirates with the main sectign.

2. A plumbing tting comprising combined Waste and vent section having a` main inlet connetionnt the lower' end thereof, ,a second inlet connection substantialiy Within the vertical aree of the main inlet, ar Vent member Communicating with seid second inlet and with the waste and rent section and related to said main and second inlet to Ventilate .the same and en inlet communicating directlyT with the combined Waste and vent Section it zr point intermediate the main and second inlets and the point of exhaust of seid vent.

3. En e combination Weste and Vent fitting,

., JP IPAQ A er wie patent enea the combination of e stack, a main inlet member communicating With and at an angular relation to the lower end of the stack, a secondary inlet member communicating with the stack Within siphoning distance of a. main inlet, a. Vent duct communicatinget its lower end with the said secondary inlet member :and communicating at its upper end with the stack at a, distance above the siphonng area of the main inlet connection, 1

and an inlet member connected directly to the stack intermedia-te of the upper and lower ends of said Vent duet so es to discharge directly into the stack, intermediate of the ends Aof said rent duet.r

in testimony whereof I have vaiiixed my signature in presence ot two Witnesses.
